Abstract
Aspects of this disclosure relate to a radio frequency module with a radio frequency coupler and a coupler switching circuit. The coupler switching circuit can provide an indication of radio frequency power generated by the radio frequency coupler to a first input/output port. The coupler switching circuit can also pass an indication of radio frequency power received at the first input/output port to a second input/output port, and pass an indication of radio frequency power received at the second input/output port to the first input/output port.
Claims20
A radio frequency module comprising:
- a first input/output port;
- a second input/output port;
- a radio frequency coupler;
- and
- a coupler switching circuit configured to pass an indication of radio frequency power received at the first input/output port to the second input/output port, pass an indication of radio frequency power received at the second input/output port to the first input/output port, and provide an indication of radio frequency power from the radio coupler to the first input/output port.
The radio frequency module of claim 10 wherein the plurality of switches includes a switch configured to selectively electrically connect a termination impedance to a port of the radio frequency coupler.
A radio frequency system comprising:
- a first radio frequency module including a first port and a first coupler switching circuit;
